HochdruckreiriigUngsgerätHigh pressure cleaning device

Die Erfindung betrifft ein Hochdruckreinigungseerät bestehend eye einen! druckerzeugender: Aggregat mit angeschlossener Spritzpistole.The invention relates to a high-pressure cleaning device comprising a pressure-generating unit with a connected spray gun.

Bekannt sind derartige Hochdruckreinigungsgeräte und zwar in verfahrbarer und auch in einer tragbaren Ausführung. Zum Erzeugen des Druckes werden Kolbenpumpen und zwar insbesondere Achsial-Kolbenpumpen oder Reihen-Kolbenpumpen verwendet. Der wesentliche Nachteil besteht darin, daß diese bekannten Geräte umständlich zu handhaben sind, in dem das eigentliche Druckaggregat in einem Fahr- oder Traggestell angeordnet ists an dem dann die Spritzpistole angeschlossen wird. Diese bekannten Geräte sind insbesondere auch dann schlecht zu handhaben, wenn sie an verschiedenen Einsatzorten betrieben werden sollen. Durch den notwendigen Anschluß der Geräte an einen Hochdruckschlauch ist der Aktionsradius eingeschränkt. Weiterhin sind die bekannten Geriite kostenaufwendig und es sind eine Reibe von Anschlüssen herzustellen, damit die Geräte funktionsfähig sind.Such high-pressure cleaning devices are known in both mobile and portable versions. Piston pumps, particularly axial piston pumps or in-line piston pumps, are used to generate the pressure. The main disadvantage is that these known devices are difficult to handle, as the actual pressure unit is arranged in a trolley or support frame to which the spray gun is then connected. These known devices are particularly difficult to handle if they are to be used at different locations. The radius of action is limited by the need to connect the devices to a high-pressure hose. Furthermore, the known devices are expensive and a large number of connections must be made in order for the devices to function.

Der Erfindung liegt die Aufgabe zugrunde, ein Geräte der bekannten Art so auszubilden, daß es als einfaches Handgerät mit der WasserleitungThe invention is based on the object of designing a device of the known type in such a way that it can be connected to the water pipe as a simple hand-held device

Und gegebenenfalls mit dem Stromnetz verbunden» gebrauchsfertig wird.And if necessary connected to the power grid, it is ready for use.

Diese Aufgabe wird nach der Erfindung däduroh gelöst, daß das Druckaggregat, bestehend aus einer Pumpe und einem Elektromotor in den Kopf der Snr i t znistola ei nhosvoonn linrl &Lgr;&agr;&kgr; Pumnonoo—This object is achieved according to the invention in that the pressure unit, consisting of a pump and an electric motor, is installed in the head of the pressure vessel and has a pressure relief valve &Lgr;&agr;&kgr; Pumnonoo—

Eine vorteilhafte Ausführungsform besteht darin, daß der Elektromotor von einer Batterie oder aus dem Stromnetz gespeist ist.An advantageous embodiment consists in that the electric motor is powered by a battery or from the power grid.

Weiterhin ist Vorgeschlagen, daß als Pumpe eine Achsiälkolbenpumpe vorgesehen ist.It is further proposed that an axial piston pump be used as the pump.

Es wird weiterhin vorgeschlagen, daß die Pumpe eine feststehende Taumelscheibe aufweist, der eine mit Achsialkolben versehene angetriebene Scheibe zugeordnet ist, wobei die Kolben an der schrägen Fläche der Taumelscheibe geführt sind und daß die Kolben an einer Dichtscheibe mit kreisförmig angeordneten Schlitzen mit ihrer Druck- und Saugseite verbunden sind.It is further proposed that the pump has a fixed swash plate, to which a driven disk provided with axial pistons is assigned, the pistons being guided on the inclined surface of the swash plate and the pistons being connected to their pressure and suction sides on a sealing disk with circularly arranged slots.

Eine weitere vorteilhafte Ausführungsform sieht vor, daß zwischen der Druckseite und der Saugseite ein Überdruckventil angeordnet ist.A further advantageous embodiment provides that a pressure relief valve is arranged between the pressure side and the suction side.

Die Erfindung bringt den Vorteil, daß das Gerät einfach zu handhaben ist, wobei der Aktionsradius ohne wesentliche Verminderung der Leistung nahezu beliebig verlängert werden kann. Günstig für dieThe invention has the advantage that the device is easy to handle, and the operating radius can be extended almost as desired without significantly reducing performance. This is beneficial for

liandhabung ist auch das niedrige Gewicht des Gerätes. Die gedrängte Bauform des Gerätes Wird auch durch die besondere Konstruktion der Pumpe begünstigt.Another advantage of the device is its low weight. The compact design of the device is also helped by the special construction of the pump.

ß) Die Erfindung Wird in der nachfolgnden Beschreibung anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher erläutert. ß) The invention is explained in more detail in the following description using an embodiment shown in the drawings.

Die Figur 1 zeigt eine derartige Spritzpistole, wobei an dem Handgriff 1 das Pümpengehäuse 2 an-,geordnet ist, an dem Weiterhin ein Motor 3 angebracht ist. Am Pumpengehäuse 2 ist weiterhin ein Ventilgehäuse 4 mit einem Spritzrohr 5 und einer Spritzdüse 6 befestigt. Am Ventilgehäuse 4 ist ein Wasserschlauch 7 angeschlossen, wobei weiterj hin an geeigneter Stelle der elektrische Anschluß für den Motor 3 vorgesehen ist. Am Handgriff 1 be-Figure 1 shows such a spray gun, with the pump housing 2 being arranged on the handle 1, to which a motor 3 is also attached. A valve housing 4 with a spray pipe 5 and a spray nozzle 6 is also attached to the pump housing 2. A water hose 7 is connected to the valve housing 4, with the electrical connection for the motor 3 also being provided at a suitable location. The handle 1 has

findet sich weiterhin ein Handschaltef 9.There is still a manual transmission 9.

Die Figuren 2 und 3 zeigen die besondere Ausführungsform der verwendeten Achsialkolbenpumpe, wobei an den Motor 3 eiiie feststehende Taumelscheibe 10 angeflanscht ist. An dieser Scheibe 10 ist die Pumpenwelle 11 gelagert, wobei weiterhin an dieser Scheibe 10 das Pumpengehä'use 2 angeflanscht ist. Mit der Welle 11 ist eine angetriebene Scheibe 12 verbunden, in der mehrere Kolben 13» bei dem gezeigten Ausfiihrungsbeispiel sind es vier Kolben 13, verschiebbar geführt sind. Der Kopf 14 der Kolben 13 liegt an der schräggestellten Fläche 15 der Scheibe 10 an. Der Andruck erfolgt mit Hilfe von Federn 16. An der angetriebenen Scheibe 12 ist abgedichtet eine Gleitscheibe 17 befestigt, die an einer am Pumpengehäuse 2 befestigten Dichtscheibe 18 anliegt. Die Dichtscheibe 18 verbindet die Zylinder der Kolben 13 mit dem Saugkanal 19, bzw. dem Druckkanal 20. Zwischen den beiden Kanälen befindet sich ein Überdruckventil 21. An den Druckkanal 20 ist das Spritzrohr 5 und an den Saugka^a1 19 der Wasserschlauch 7 angeschlossen. Der Antrieb der Welle 11 für den Motor 3 erfolgt über ein UntersetzungsgetriebeFigures 2 and 3 show the special embodiment of the axial piston pump used, in which a fixed wobble plate 10 is flanged to the motor 3. The pump shaft 11 is mounted on this plate 10, and the pump housing 2 is also flanged to this plate 10. A driven plate 12 is connected to the shaft 11, in which several pistons 13 - in the embodiment shown there are four pistons 13 - are slidably guided. The head 14 of the pistons 13 rests on the inclined surface 15 of the plate 10. The pressure is applied by means of springs 16. A sliding plate 17 is attached in a sealed manner to the driven plate 12, which rests on a sealing plate 18 attached to the pump housing 2. The sealing disc 18 connects the cylinders of the pistons 13 with the suction channel 19 and the pressure channel 20. Between the two channels there is a pressure relief valve 21. The spray pipe 5 is connected to the pressure channel 20 and the water hose 7 is connected to the suction channel 19. The shaft 11 for the motor 3 is driven by a reduction gear.

In der Dichtscheibe 18 sind kreisförmige Schlitze bzw. 24 angeordnet. Diese Schlitze gewährleisten, daß die Zylinder der Kolben 13 während ihrer Sehu!>üewegung mit dem Auslaß 20 und während ihrer saugendenCircular slots 24 and 25 are arranged in the sealing disk 18. These slots ensure that the cylinders of the pistons 13 during their suction movement with the outlet 20 and during their suction

Bewegung mit dem Anschluß 19 verbunden sind. Durch die Verwendung einer derartigen Dichtscheibe 18 in Verbindung mit der feststehenden Taumelscheibe 10 wird erreicht, daß Ansaug- und Druckventile entfallen können und damit auch eine besonders platzsparende Ausgestaltung der Pumpe möglich ist.Movement is connected to the connection 19. By using such a sealing disk 18 in conjunction with the fixed wobble plate 10, it is achieved that suction and pressure valves can be omitted and thus a particularly space-saving design of the pump is possible.
